The 480D25-HS is a DC-controlled HS Series relay that switches 480 VAC at up to 25 A. This SSR features an integrated heatsink. Because there is less thermal resistance internal to the unit than in a standard SSR mounted to the same heat sink, heat dissipates more easily. The built-in heatsink means you don't have to select a heatsink, and installation is much easier.

Each HS-series SSR has built-in hardware for screw mounting and a built-in DIN-rail adapter clip for mounting to a 35mm DIN rail.

HS Series relays provide 4000 volts of isolation between input and output, and offer zero-voltage turn-on and zero-current turn-off. They are UL recognized and are a CE component.
